I need to combine two 3.5mm audio signals into one to plug into my computer and record. My strategy was going to be to buy 2 3.5mm to RCA adapters for each input, a 2-channel RCA audio mixer that outputs RCA, and then another RCA to 3.5mm converter to get it back to 3.5mm and plug it into the computer. I wanted to make sure there weren't any major flaws with this idea or if there is a cheaper option (<$58.95+shipping). Thanks!
